In some embodiments, the receptacle 128 may include at least one of (i) one or more openings or (ii) one or more protrusions. The openings and protrusions are coupled to the chassis 102 and may be location on a bottom 108, the sides 104, 105 or the top 106 of the server rack. In some embodiments, the openings may be located on the front 112 or back 114 of the server rack 100. The receptacle 128 may include the indices of alignment 126, 127. The moveable server rack 100 may include robot indices of alignment 130, 131 coupled to the chassis 102 and to align the mobile robot 170 in the receptacle 128. The moveable server rack 100 may include two or more support bodies 124 coupled to the chassis 102 and located on a bottom 108 of the server rack 100 and spaced to provide an open space under the server rack. The open space may allow the receptacle 128 to couple with the mobile robot 170 and to allow the mobile robot 170 to lift the server rack 100 when coupled to the receptacle 128.

In some embodiments, the moveable server rack 100 may be moved by a mobile robot 170 with a configuration that allows the mobile robot 170 to grip and/or engage the sides 104, 105 of the moveable server rack 100. For example, the sides 104, 105 may include an indentation, ledge, or longitudinal channel to allow the mobile robot 170 with protruding arms to engage the moveable server rack 100 and lift it for moving to a second docking location. As another example, the mobile robot 170 may engage the moveable server rack 100 on the sides 104, 105 by application of pressure to the sides and then lift the moveable server rack 100 by maintaining sufficient pressure against the sides 104, 105. As another example, the mobile robot 170 may straddle over the top of the moveable server rack 100 and engage on the top 106 and/or the sides 104, 105 of the moveable server rack 100 and lift the moveable server rack 100 to move it to a second docking location. As another example, the moveable server rack 100 may have holes on the sides 104, 105 to receive protrusions of the mobile robot 170 extended inside the holes when the mobile robot 170 is aligned with the moveable server rack 100. The moveable server rack 100 may have any number of holes or protrusions located on the sides 104, 105, the top 106, and/or the bottom 108 to couple with the mobile robot 170 to allow the mobile robot to move the moveable server rack 100. The mobile robot 170 may have longitudinal devices similar to a fork lift to engage the moveable server rack 100 in order to move the rack 100.

In some embodiments, the moveable server rack 100 may include a wheel system where the mobile robot 170 engages the moveable server rack 100 and rolls the moveable server rack to a second docking location. In some embodiments, the moveable server rack 100 may include the wheel system where the mobile robot 170 engages the moveable server rack 100 and may move the moveable server rack 100 to the second docking location by a combination of lifting and rolling of the moveable server rack 100.

In some embodiments, the robot 170 may remain coupled to the moveable server rack 100 before and after moving of the rack 100. In some embodiments, the robot 170 may be a component of the moveable server rack 100 and coupled to the chassis 102.

In some embodiments, the servers 110 of the moveable server rack 100 may include servers with the same or similar functionality or focus to provide a substantially homogeneous set of servers 110 or may be servers with a variety of functionalities or focuses to provide a heterogeneous set of servers 110. For example, servers 110 may include storage, compute, input/output, field-programmable gate array (FPGA) custom accelerators, CODECS, load balancers, security (honeypot, honeynet, and/or demilitarized zone areas), encryption/decryption, voice recognition, global positioning systems (GPS), music, high performance computing cluster, and/or video, and the like.

In some embodiments, the servers 110 may be selected for a moveable server rack 100 based upon historical usage data (usage data) including the type of functionality or focus required during selected periods of time in order to optimize data center performance. Usage data may include power consumption data, input/output (I/O) data (I/O traffic), number of packets sent and/or received, bandwidth data, number of hits, and the like. Usage data may include any data relevant to optimizing performance of a data center and may relate to individual servers 110 and racks 100. Optimizing data center performance further may include optimizing servers 110 selected for different racks 100, where the racks 100 may be located in optimal docking locations based upon anticipated data center traffic needs.

For example, a data center providing services related to stock market trading may select servers 110 for the moveable server rack 100 to optimize performance of rack 100 for stock market trading during a selected period of time that a stock market is open for trading. This rack 100 may be located in a docking location of the data center to provide low latency in order to optimize performance of the data center during the trading window. During off hours of trading, the rack 100 may be moved to another docking location in the data center and used for other services not requiring low latency.

As another example, a moveable server rack 100 may have servers 110 selected to optimize video streaming. The rack 100 may be located in a docking location to optimize delivery of video streaming services during a high demand period, such as a Friday or Saturday evening. When data center usage data indicates that video streaming services may decline at a certain time, the data center rack controller 150 may issue commands to the robots 170 to move one or more racks 100 with video streaming focus to other docking locations in the data center. For example, the data center controller may determine, based on historical usage data, that one or more storage focused racks 100 may be needed in the docking locations occupied by the racks 100 with a video streaming focus and may swap the racks 100 via robots 170.

In some embodiments, moveable server racks 100 may be moved from a first location to a second location that may be one or more switch hops away from the first location, based upon usage data in order to optimize data center performance. For example, a switch hop may be about 8% difference in latency, and a rack 100 needing low latency during a certain period of time may be moved closer to a router or load balance prior to the beginning of the time period of needing the low latency. This move may be determined by the controller 150 to provide better overall performance of the data center.

In some embodiments, one or more moveable server racks 100 may include a GPS function. The amount of GPS function in rack 100 may be variable, depending on usage data. For example, usage data may indicate that certain morning hours and/or after work hours have higher GPS service demand. The controller 150, in order to optimize data center performance, may determine that a rack 100 may be configured with servers 110 with more GPS focus and locate those racks 100 in lower latency docking locations in the data center during the higher GPS demand periods. These same racks 100 may further have other focus services such as input/output focus to meet other demands on the data center during the same period of time. During periods of time with GPS services may be less in demand, the racks 100 located in low latency docking locations may contain servers 110 with GPS functionality but the overall focus of the rack 100 may not be to provide GPS services. For example, a rack 100 with a stock market trading focus may have GPS functionality to meet a lower GPS service demand during the trading hours. This GPS functionality provides low latency to the fewer customers needing the service during the overall lower GPS demand period.

In some embodiments, the data center rack controller 150 may improve data center performance by moving a moveable server rack 100 from a first docking station to a second docking station based on a need for more of a particular function or focus of the moveable server rack 100. For example, a moveable server rack 100 may have a storage focus that may be needed at a selected period of time such as a period of time in which storage functionality is in high demand in the data center.

In some embodiments, the data center rack controller 150 may improve data center performance by swapping a first moveable server rack 100 with a second moveable server rack 100 because the first rack is determined to be a bottleneck to performance of the second rack resulting in overall lower performance of the data center. For example, the second rack may have an input/output focus for video streaming and the first rack may have a compute focus. The controller 150 may determine that, during a selected period of time such as a Friday or Saturday evening, switching the first rack with the second rack may improve data center performance because there is more demand during the selected period of time for the input/output focus for video streaming.

In some embodiments, the data center controller 150 may improve data center performance by moving moveable server racks 100 to provide a more optimal heat distribution in a data center, in accordance with the cooling configuration of the data center. For example, controller 150 may determine that one or more compute focused racks may be under high demand and generating too much heat for the location in the data center. The heat generated may result in a need to reduce performance of the one or more compute focused racks unless the racks are moved to a location in the data center having better cooling. The controller 150 may issue commands to one or more robots 170 to move the one or more compute focused racks to docking stations with better cooling in order to maintain optimal overall performance of the data center.

In some embodiments, the moveable server rack 100 may be a new rack that is configured with a number of servers 110 and then moved by a robot 170 to a docking location in a data center to operate within the data center. In some embodiments, the moveable server rack 100 may be moved by the robot 170 from a first docking location to a maintenance location for maintenance and/or replacement of one or more servers 110 or components of the rack 100. The rack 100 may be moved by the robot 170 back to the first docking location or to a second docking location after work is completed at the maintenance location, as determined by the data center rack controller 150 based upon usage data and the functionality or focus of the rack 100.

In some embodiments, the controller 150 may use current events data, such as a sporting event, and issue move commands to the robots 170 to move one or more racks 100 in order to meet anticipated demands for services related to the current event. In some embodiments, the current events data may be considered with usage data in order to optimize data center performance, where the controller 150 may issue move commands to the robots 170 to move one or more racks 100 based upon the anticipated services required for the current event and the usage data.

In some embodiments, a customer of a data center may pay a premium to have selected racks 100 moved to low latency locations in the data center during certain periods of time. The payment of a premium may alter the optimal location of racks 100 and selection of servers 110 for a rack 100 to provide a new optimal server 110 selection and rack 100 docking location. In accordance with the new optimum of servers 110 and rack 100 location, the controller 150 may issue commands to select servers 110 of a certain functionality for one or more racks 100 and may issue commands to one or more robots 170 to move the one or more racks 100 to low latency docking locations in the data center for certain periods of time.

In some embodiments, the moveable server rack 100 may include a rack controller 122 coupled to the chassis 102 and with a processor 122.1, a memory 122.2, a transmitter 122.4 and a communications port 122.3 and a receiver 122.4. The moveable server rack 100 may include one or more sensors 119 coupled to the controller 122. The controller 122 may receive one or more signals from the one or more sensors 119, where the signals may be processed by the processor 122.1 using the memory 122.2. The signals may provide the indication of docking alignment. The controller 122 may transmit wirelessly via the transmitter 122.4 or transmit wired via the communications port 122.3 over the data center network, the indication of docking alignment to the data center rack controller 150.

The sensors 119 may include temperature sensors. Data from the temperature sensors may be transmitted to controller 150, and controller 150 may issue one or more commands to robots 170 to move racks 100 based upon the temperature data in order to optimize performance of the data center. Move commands may allow racks 100 with high demand and usage to be moved to docking locations with better cooling in order to maintain speed of the servers. In some embodiments, the controller 150 may issue move commands to robots 170 to move one or more racks 100 based upon power data consumption in order to prevent overloading circuits of a data center.

In some embodiments, the controller 122 may receive wirelessly via the receiver 122.4 or may receive wired via the communications port 122.3 coupled to a mobile robot communications port 172, the indication of docking alignment from the mobile robot. The controller may transmit wirelessly via the transmitter 122.4 or transmit wired via the communications port 122.3 over the data center network, the indication of docking alignment to the data center rack controller 150. In some embodiments, a restraint coupling 132 may be coupled to the chassis 102. The restraint coupling 132 may automatically secure the server rack 100 when the server rack 100 is docked at the second docking location and may automatically unsecure the server rack 100 when the server rack 100 is undocked from the first docking location. The restraint coupling 132 may secure the server rack to or from a wall, ceiling, or floor, or combination thereof, of the data center. In some embodiments, the server rack 100 may have the power connector 120 and the I/O connector 121 as a single connecter, where the single connector is to couple or decouple automatically to a mate single connector of the data center. In some embodiments, a battery 117 may be coupled to the chassis and may provide temporary power to the plurality of servers 110 when the server rack 100 does not have a power source to supply power to the power connector system 116, 120. In some embodiments, the battery 117 may be a super capacitor or combination of a battery and a super capacitor or some other type of temporary power source. In some embodiments, the plurality of servers may maintain at least network addresses via the battery 117.

In some embodiments, a first moveable server rack 100 may have network addresses and other server related data preserved by use of the battery 117. A second moveable server rack 100 may be swapped with the first rack using one or more robots 170. After the first server rack is in the new docking location, power may be restored to the first server rack and then the network address and other server related data preserved using the battery 117 may be restored to provide the first server rack functionality as it had prior to being swapped with the second rack.
